Measurement of the (197)Au(n,gamma) cross section at n_TOF : towards a new standard
(EDP Sciences, 2008)
Two different detectors and techniques are employed at n_TOF facility, at CERN, to improve the accuracy of the neutron capture cross section of (197)Au(n,gamma): a total absorption calorimeter and a Set Of C(6)D(6). The ...
Measurement of neutron induced fission of (235)U, (233)U and (245)Cm with the FIC detector at the CERN n_TOF facility
(EDP Sciences, 2008)
A series of measurements of neutron induced fission cross section of various TRU isotopes have been performed at the CERN n_TOF spallation neutron facility, in the energy range from thermal to nearly 250 MeV. The experimental ...
Capture cross section measurements of (186,187,188)Os at n_TOF : the resolved resonance region
(EDP Sciences, 2008)
The neutron capture cross sections of (186,187,188)Os have been measured at the CERN neutron time-of-flight facility, n_TOF, in the neutron energy range from 1 eV up to 1 MeV. In this contribution, we report the results ...
The (234)U neutron capture cross section measurement at the n_TOF facility
(EDP Sciences, 2008)
The neutron capture cross-section of (234)U has been measured for energies from thermal up to the keV region in the neutron time-of-flight facility n_TOF, based on a spallation source located at CERN. A 4 pi BaF(2) array ...
Measurement of the radiative neutron capture cross section of Pb-206 and its astrophysical implications
(2007-10)
The (n,gamma) cross section of Pb-206 has been measured at the CERN n_TOF facility with high resolution in the energy range from 1 eV to 620 keV by using two optimized C6D6 detectors. In the investigated energy interval ...
Status and outlook of the neutron time-of-flight facility
(2007-08)
The neutron time-of-flight facility n_TOF at CERN, fully operational since 2002, combines a high instantaneous neutron flux with high energy resolution. The wide energy range and the high neutron flux per time-of-flight ...
Neutron reactions and nuclear cosmo-chronology
(Elsevier, 2007-07)
The beta-decay of Re-187 (t(1/2) = 42.3 Gyr) represents a suited cosmo-chronometer for the age of the r-process abundances, since the radiogenic part of the daughter isotope (OS)-O-187 is defined by the difference between ...
The La-139(n,gamma) cross section : Key for the onset of the s-process
(2007-03)
The nuclear resonance parameters and the capture cross section of the neutron magic isotope La-139 have been measured relative to Au-197 in the energy range of 0.6 eV to 9 keV at the neutron time-of-flight (n_TOF) facility ...
Measurement of the neutron capture cross section of the s-only isotope Pb-204 from 1 eV to 440 keV
(2007-01)
The neutron capture cross section of Pb-204 has been measured at the CERN n_TOF installation with high resolution in the energy range from 1 eV to 440 keV. An R-matrix analysis of the resolved resonance region, between 1 ...
Measurements of neutron capture cross-sections at n_TOF
(American Institute of Physics (AIP), 2007)
Capture cross-sections on isotopes relevant to accelerator driven systems for energy production and nuclear waste transmutation, and to stellar nucleosynthesis have been studied at the innovative neutron time of flight ...
